[libvirt] VM Migration with IEEE802.1Qbh and IEEE802.1Qbg

Hi All, Can a VM connected as IEEE802.1Qbh be migrated to a destination host as it were connected as IEEE802.1Qbg? What I wanted to know is, is it possible to change the configuration from IEEE802.1Qbh to IEEE802.1Qbg on the fly? Regards Jagath
